People can now view how storm overflow activity across the region is changing.
Southern Water has replaced its existing Beachbuoy online tool with the new Rivers and Seas Watch platform.
It will feature every single combined sewer outfall – also known as storm overflows – along the 700 miles of coastline and the scores of rivers and streams which cross Kent, Sussex, Hampshire and the Isle of Wight.
The new tool uses advanced modelling of tides, currents and winds to provide more information of the possible impact of storm releases to local water quality.
Tom Gallagher, open water improvement lead, said: “There are major improvements to the look and feel of the site and each outfall is colour coded as before.”
Users can make the most of this service by signing up for alerts for their local beaches, as data protection rules mean previous Beachbuoy users cannot be carried over.
